Story telling is better then bragging
I like this spot, because it shows you what you can do with the product rather then braging about the technical aspects. To use the 3D-Card to show a before and after is not very creative (is ment to do that), but to tell a story where the twist is caused by the features the card has is very clever.
One small flaw is in the spot. How did the postman know that he is the right person? There was no stamp and no address on the back?
